Civil Engineering and CSE are the trendiest branches as reckoned by the leading companies. If you will opt for a better college over a preferred branch for pursuing engineering then it is suggested to switch your opinion. 

Seeing this, you must choose Civil Engineering at Jadavpur University over KGEC. Following are the reasons for choosing the same:

• The faculty at Jadavpur University is comparatively better than Kalyani Government College. They are well-experienced and most of the faculty members hold a doctorate degree. 
• The student crowd at JU is helping and competitive. One of the main highlights is the students’ club in the university. You will receive good exposure.
• Although the placement scenario for the civil industry is deteriorating in the entire nation, it is still better to take it up at Jadavpur University than Kalyani for CSE. 
• The mass recruiters are mainly limited to companies such as TCS, Infosys, etc. at Kalyani. Whereas in JU, you would be able to opt for financing and consultancy firms as well. They certainly provide contenting packages.

It is suggested that you choose your preferred stream if you ultimately have planned on pursuing higher studies like GATE, GRE, etc. If you are planning on doing MBA or some job then JU would be the best fit. 

You should keep in mind that the name tag of your undergraduate institute always stays with you hence choose wisely.
